Fig. 15 is a detailed section of the receiving means for the yarn stick, shown at the right hand side ofFig. 12 while Fig. 16 is a detailed-section of the receiving means for-the yarn stick shown at the left hand side of Fig. 12. i Referring more particularly to Figs. 1-'-9, it will be seen that the dyeing ap aratus comprises a base 1 having ends 2 an 3and sides 4 and 5. A movable top portion is shown at 6. If desired the top portion: may be hinged, as at 6a. "As will be seen from Fig; 2, theidyeing apparatus is divided into an agitating chamber 7 and a dyeing chamber 8, by means of a divisionplate' 9.

At thetop and bottom of the effective pora tions of the dyeing chamber are perforated plates 10 and,11,'respectivel {The top plate is supported b means which will be described later, 'whi e the bottom plate is in part supported by members 12 of channel or other suitable form. T

Carried by transverse beams 13 andl, to which lift-ing eyes "15and '16 may be at-" tached, are longitudinally extendin beams 17 and 18. Secured to beams 17 an 18 are hangers 19, 19 and 20, 20, from which is supported a yarn rack. V

Formerly, when using wooden dyeing racks, the material on which the yarnsticks were; sup orted was usually more than two inches thick thus furnishing suflicientbear ing surface for the yarn sticks. Whenso constructed the yarn sticks seldom, if ever, dropped out. Now however, it is found desirable to make yarn racks ofmetal, of thickness generally about one-eighth inch, which affords very little bearing surface for the 'yarn sticks. When so constructed, a very slight swaying of the yarn rack will cause the sticks to slip out of'the holes, especiallyas they are more slippery than-the wooden sticks. To avoid V this, angles such asshown at 21 at the right hand side of Fig.4 have been employed'mside the yarnrack on both sides. However, this madeit necessary to enlarge the stick holes to an objectionable degree in order to 109 studs 30 may As shown in Fig. 4, I accomplish this ob- "ject by placing a Z-bar 22 on the outside of yarn rack 23; The yarn stick 24, loaded with yarn, is then inserted in the hole 25 in the yarnrack, where it rests on the angle 26,

and is then slipped back past angle 21 until i it rests upon and abuts the Z-bar 22. It will be noted that the Z-bar prevents the yarn sticks Zfrom dropping out or being drawn through the hole 27.

: lVith this arrangement, it is necessary to lock the sticks into position on the opposite side of the yarn rack. In the present instance, the locking means takes the. form of a locking plate 28. This plate is provided with preferably L-shaped slots 29, throu which are inserted metal studs 30. Tie beinserted into the hangers or into bloc s attached to the yarn rack for that purpose.

By means of a sliding fit on the. studs 30, the locking plate-can be moved side-wise, and elevated or dropped, as the occasion requires. To further secure the locking plate into position, a plurality of straps 31 of any suitable material are provided. As illustrated in Fig. 5, this strap comprises the U-shaped elements 32 and 33, secured togetherat their ends, and between which the locking plate 28 is vertically guided.

At varioustimes while the skeins are under treatment, it ,is necessary to take samples, and in order to do so, the locking plate must beelevated to permit removal of a skein from one endof the yarn stick. When the yarn rack is lifted from boiling. or hot solutions, the locking plate will be heated to about the temperature of the solution. Accordingly the bars 17, and 18 are interposed between the hangers 19 and 20 and the handles l5and 16, and since these bars. are of wood or other suitable insulators, they act as effective heat insulators J Of course, it is understood that the dyeing apparatus is susceptible to use in a var iety of sizes and shapes.

As will be noted in Figs. 4 and 5, the ends of the yarn rack are preferably bent outwardly to form flanges 34. These flanges aredesigned toprevent the flow of dyeing liquorbetween the inside of the vat and the outside of the yarn rack when the rack is seated in the vat. They are further designed to extend outjust far enough to serve as aprotection for the Z-bar on one side, and the angle, locking plate, and stud on the other side,;in orderthat the parts referred to will not catch on the top of the dyeing chamher when the yarn rack is being entered therein.

The propeller chamber may be subdivided into one or more chambers 35 for the reception of propeller shafts and blades. These chambers are defined by a plate 36 having a. plurality of openings. (one for each propeller), straps or hangers 37, and walls 4, 5

and top portion 38. By supporting the propelle'rplate-36 from hangers the necessity of Ina-king holes through the dyeing chamber and lining is avoided.

It will be noted that the top 39 of division plate 9 is rolled back, in order that skeins will not become engaged with it when the yarn is lifted in or out of the machine. The bottom of the division plate-9 is flanged inwardly at 40 towards the dyeing chamber, the perforated plate 11 resting on the flange. The division plate is carried by any suitable means, such as angles (not shown) on the side walls. r Despite the use of my improved form of yarn rack, the holes for the yarn sticks are of necessity, still somewhat larger than the yarn sticks. Because of this, when the dyeing liquor is circulated, a portion of the skeins adjacent the side of the yarn rack is carried by circulation into and through the holes in the side.

When the flow of dyeing liquor is reversed, it will be seen that the yarn. stick is carried up or down with the liquor, and such yarn as has been carried. into the yarn stick hole is likely to be pinched by the warn stick ,and result in anundyed or untreated place; or with the rise and fall of the yarn stick and especially with fine counts of yarn, the yarn may be cut or weakened as a result of the weight and pressure of the stick against the '1;

A metal lining 42 is provided throughout the apparatus, to prevent the liquor becom ing clouded by reaction with the wood casing.

Referring more particularly to Figs. 1046, it will be noticedthat the outturned flanges 34 of yarn rack 27 are upturned as at 43, creating a round and smooth surface, and overcoming gouging or cutting as would be the case with a straight edge. In order to permit the liquor to drain out as the yarn rack is lifted from the dyeing'chamber, properly spaced perforations-.44 are provided in the flanges 34.

In this modification it has been deemed advisable to minimize the flow of liquor The wires are so located that through the yarn. stick holes, thus stopping '33 l the liquor from carrying the yarn-into the yarn stickholes and overcoming the pinching and undyed places where the yarn rack sides in the holes; It has further been found advantageousto provide means which will more eflicientlyprevent cutting of the yarn by the upward and downward motion of the yarn sticksupon reversa of the flowof the liquor.

To accomplish these purposes, there has been substituted for the Z -bar of Fig. 4, a U or other suitably shaped 'bar 45, extending substantially the full length of the yarn rack, and being provided on its under, parallel face with aplurality of properly spaced perforations 46, through which the liquor can drain upon removal of the yarn rack from the dyeing chamber. As will be noted from reference to Figs. 12, 13, and 16, angles 47 have been placed on the interior of the yarn rack on both sides to keep the, skeins away from the yarn stick holes, as a further means of overcoming the pinching, etc. In this manner the use of wires 41 is avoided.

In a further attempt to prevent scratching the lining of the apparatus members 48 are provided at both ends of one side of the yarn rack. These members haverounded edges and bottom, and are provided with grooves, to guide the locking plate 49.

The locking plate 49 is elevated by handles 50. and when in lowered position rests on the Z-bar 51, which acts as both guide and support and which has perforations 52 by means of which it can be quickly drained when lifted from the dyeing chamber. I

The locking plate 49 differs from that shown in Fig. 6, in that it is movable only in a vertical path, by means of arms 52a, journalled in the top of the apparatus.

The top of the apparatus is provided adjacent the arms 52a with hollow lug portions 53. Through the aperture therein extends the plunger 54 having an exterior head 54. Near the exterior end the aperture is interiorly threaded as at 55, which threads engage an exteriorly threaded hollow nut 56, which when in place retains a spring 57 in tension around plunger 54 by reason of its coaction with an inner head 58'formed on the plunger. The head 58 engages an aperture 59 in arm 52, thus normally retaining the locking plate in raised position. When it is desired to drop the plate 49 to rest on the Z-bar 51 the plunger 52 is retracted from engagement in the aperture 59, against the influence of spring 57, by means of outer head 53.

As will be readily apparent, this invention is susceptible to numerous modifications, and it is intended that it be limited only by the scope of the appended claims.
